Konica Minolta Printer Manager and Tray Icon
I have a Konica Minolta 2300W color printer directly attached to my computer via parallel port. The desktop has a Konica printer manager that watches the toner levels and you'd use this utility to rotate the toners to swap them out respectively. Well one of the toner cartridges started running empty and so the printer management utility started graphically highlighting the near-empty toner cartridge in red. It was right around this time when the toner was running out that I started noticing "MSTMON_P.EXE has encountered a problem and needs to close. We are sorry for the inconvenience." mes
